8 years ago, my son decided to turn breech-bottom down-at 37 weeks, too. A successful pregnancy after 4 miscarriages, I had every crazy thing happen that you don't want to happen...like questionable gestational diabetes, placenta previa until about week 33, among other things, but he was head-down and the placenta was out of the way enough to have a vaginal birth. Then one night 18 days before his due date, he was flipping around, doing somersaults all night long, until my water broke at 5:30am, and we headed to the hospital. The sonogram showed he was breech, just 2 days after being head-down at my office visit! So they walked me down the hall to have a C-section, and I was mad and sad. It was quickly discovered that my son, in all his flipping and turning, had tied not one, but TWO full knots in his umbilical cord, and it was wrapped around his neck, which is hardly every seen without some complications. They came around and showed me the knots in the cord, and we then realized what a blessing it was that my little boy had caused all that commotion, turned breech, and made my water break so he could get out quickly. If we had tried a vaginal breech birth, or if he had been turned, the pushing would have likely cut off his oxygen and been very dangerous for us both. My little boy was only 5'15"at birth, but he's been a bundle of healthy energy, and God's blessing to us for 8 years. And our 2nd blessing, a little girl 2 years later, was a VBAC (vaginal birth after c-section), so I got to have my normal, painful (until the epidural) labor, and pushed her out in 22 minutes. Good luck with your breech baby boy, and even if a C-section is necessary, it might be for a good reason.
